HC1-H-AC24V-F Equivalent & Substitute Parts

Part Overview

The HC1-H-AC24V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 24VAC coil and 10A contact rating. This socketable relay is designed for standard industrial switching applications with a maximum switching voltage of 250VAC. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC1-H-AC24V-F is determined by the following critical parameters:

• Coil Voltage: 24VAC (exact match required)
• Contact Form: SPDT (1 Form C) configuration
• Contact Rating: 10A minimum
• Mounting Type: Socketable with plug-in termination
• Coil Type: Non-latching operation
• Operating Voltage Range: Must accommodate 19.2 VAC minimum operate and 7.2 VAC maximum release thresholds

The G2R-1-S AC24(S) from Omron Automation and Safety meets all substitution criteria. This relay maintains electrical compatibility through identical coil voltage, contact configuration, and current rating, while offering enhanced performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The G2R-1-S AC24(S) is the direct substitute for the obsolete HC1-H-AC24V-F. Both relays share identical electrical specifications for coil voltage, contact configuration, current rating, and operating thresholds, ensuring functional compatibility in existing circuits.

The Omron substitute offers advantages in product availability and compliance status. The G2R-1-S AC24(S) maintains active product status with RoHS compliance certification, supporting long-term supply chain reliability. The substitute demonstrates improved switching performance with reduced operate and release times (15 ms and 10 ms respectively versus 20 ms each), and lower coil current consumption (37.5 mA versus 50 mA), resulting in reduced power dissipation.

The G2R-1-S AC24(S) supports an extended maximum switching voltage rating (440VAC, 125VDC) compared to the original 250VAC specification, providing greater application flexibility without compromising compatibility. Both relays carry identical ECCN classification (EAR99) and HTSUS codes, maintaining regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can the G2R-1-S AC24(S) directly replace the HC1-H-AC24V-F in existing applications?

A: Yes. Both relays share identical coil voltage (24VAC), contact configuration (SPDT), current rating (10A), and operating thresholds (19.2 VAC operate, 7.2 VAC release). The socketable mounting and plug-in termination are compatible. The substitute is a direct functional equivalent.

Q: What are the key differences between these two relays?

A: The primary differences are product status and performance characteristics. The G2R-1-S AC24(S) is an active product with RoHS compliance, while the HC1-H-AC24V-F is obsolete. The Omron relay operates faster (15 ms operate, 10 ms release versus 20 ms each) and draws less coil current (37.5 mA versus 50 mA). The substitute also supports higher maximum switching voltage (440VAC, 125VDC versus 250VAC).

Q: Are there any temperature range considerations?

A: The HC1-H-AC24V-F operates from -50°C to 70°C, while the G2R-1-S AC24(S) operates from -40°C to 70°C. For applications requiring operation below -40°C, the original specification must be verified against system requirements.

Q: Does the substitute support the same termination options?

A: Both relays feature plug-in termination for socketable mounting. The G2R-1-S AC24(S) additionally supports Quick Connect 0.187" (4.7mm) termination, providing expanded connection flexibility while maintaining compatibility with standard plug-in sockets.

Q: What is the compliance status of the substitute?

A: The G2R-1-S AC24(S) is RoHS compliant and REACH unaffected. Both relays carry EAR99 ECCN classification and identical HTSUS codes (8536.41.0050), ensuring regulatory consistency for export and procurement purposes.
